" i:teammates This. invention relates- :to ba measuring 1 device for'openings, or for; profiles, :considering a profile asgany given portion of the, external orinternal boundary of anaobjectorgan-enclosecllspace.

An objectof the invention is the: provision of a 5 device for measuring the .boundaries-ofsany open ing .so that closures which are. applied .to the opening may be cut to properly fit the opening. Another. object ofthe inventionis the provi- :sion of adevice for correctly; measuring bound: :aries-of openings so that closures may be; efiiciently fitted'into the openings in a, relatively short .,time, said device including *slidablyand. rotatably mounted bars, which are adapted to .be projectedand/or revolved in, such a m anner that the ends of the bars may beeaccurately. adjustedin contactgvvi-th the margins ,ofthe opening; so that when la straightedgej(orflexible rule); is f applied to theends ofthe bars thefoutline of the opening can be. drawn on theclosure to beiitted,

Referring more particularly to Figs. 1 to l inelusive, llljdesignates a. baseplate which may be made of meta1,;.Wood.or some. composition material which has sufficient strength and rigidityffor the purpose, The base plate is ordinarilyrectangularinshape and is providedwith a pluralityiof units carrying adjustable bars ll, 12 and I3 slidably mounted'thereon. Said units being "ordi narily located at thecorners of the base plate,

and also at points intermediate the ends of the plate; but units indanyfdesired numbergand at any desired location may be added, removed, or

re-located, as" needed. v T v v The following'is adescription of a unit} all 'unitsbeing identical: i

An inverted cup-shaped member generally designatedby the numeral 15. has a top portion l6 provided with an opening I 1. which isladapted to receive a second cup-shaped Inember generally designated by the'numera1 H8. The cup-shaped member I5 has an annular flange 19 at its lower edge and this flange is provided with a vpiurality of openings 20 to receivethreaded bolts 2|. Nuts 2-2 are threaded onto' th'e outer ends: of the bolts for clamping the flange 1.9. and likewise the Cup-sh'apedmember l5 to the...base plate ID in 'thevariouspositions shown in'Fig; 1. r

The cup-shaped member l8 has its outer end closed as shown at 25 andthis closed ortop portion has athreaded opening 26 to receive a threaded bolt 21 which has a head'28 at its outer.

end. The inner endofthemember l8 isprovided with a lateral flange -29 which is adap ted to The threaded bolt- 2'! has its inner. end received Within a pocket 34 formed in the outer face of the plate 33. i

One of the measuring bars'H-to l3 inclusive is 1 2 1f it i also inserted through the openings 39 and 3i and 1 the intermediateportion of this bar is located between the plate 33 and the top it of the member I5.

The outer ends of each of. the said measuring 2,334,385 .T [Q s bars may be semi-circular, as shown at 35, may be given any other desirable shape in manufacturing or in use and, in addition, may have separate points aflixed to them. The two ends of each bar may have difierentshapes. In general the shape of the end of the bar, or'of an attached I point, if used, will be determined by the particular requirements of the work being done.

been adjusted for a given desired clearance, and applied to the work with the inner edge 52 of the flat bar 45 resting on the edge of the door or clo- J sure 53, and the vertical flange 5| of the bar 48 vengaging the ends of the bars l2 and I3 measuring device. During the application of the device the face of the verticalflange 5| will be in'contact with the 0f the boundary of the opening equal to the clearance for which the straight-edge assembly.

It will be seen by this constructionthatthe cup-shaped member i8 is inserted through the openingll of the cup-shaped member I 5 before the annular flange I 9 has been secured to the base 7' member In. When the clamping plate 33 and a measuring bar are inserted through thealined openings and 3! in the cup-shaped ember 18,

said cup-shaped member will be maintained-in operative relation within the member l5. The tightening of the bolt-21 will cause the'clampin'g plate33'topress on themeasuring bar and thus hold the elementstogether, i When it'is desired to measure an opening such as shown at 4a in dotted linesgin'Fig. 1', itis only necessary to "place "the baseplate it within the opening and then adjustthebars Hand 12 until the outer free ends engagethe corners of the opening 41!. As each bar" is properlypositioned thebolt 21 is turned-.for clamping the bar in operative position. After the bars I I and I 2 have been properly positioned with theirends engaging the'various. corners of the'opening the bars I3 may; be similarlyadjusted outwardly iroin their supports until their free ends engage the side walls of the opening, after which the bolts 21 may be turned to secure thebars in rigid position.

sary to allow for a definite clearance so. thatthe ends of the bars I 2 and I3 and will'lie in or represent the plane of the corresponding 'partof the boundary of the opening. "The inner edge 52 of the flat bar 45 will lie at a distance from the plane 9 has been adjusted. When a pencil or scribe is employed ior drawing a line along the inner edge I 52 of the flat bar 45, said line will indicate on the door or closure 53 the part which is to be cut away to give the clearance for which the straight-edge assembly has been adjusted. When this pro-' cedure has been repeated around the perimeter of I thedoor or closure 53, the position of themeasuring-device relative to the door or closureibeing maintained unchanged by clamp or otherwise, 3 the door or. closure will bear a penciled or scribed outline along which it is adapted to be cut to give the desired clearance without further-measuring.

inner edge 52; and project inwardly 'lthere fro'm a short distance. [These straps are adaptedto give the straight-edge assembly additional bearing surfacejon the f top of the door or closure 53, and hold the bar 45 parallel to, and the flange 5| perpendicular to,'the plane oftheldooror closure 53. These straps '60 are purposely made narrow so that they will not cause material in terruptions in the penciled or scribed lines.

The foregoing description of the measuring device and its use applies'primarily tdthe fit door or other closure which-is fitted to theopening may berswung to and fro without bindinggand thatthis clearance varies with the type of work, a special formof straight-edge assembly is preferable for use'and such straight-edgeassembly is shown in Figs. Band 6'. v l r The straight-edge assembly is made preferably 7 of metal, and actually in-cludes,"in addition .to

otherparts;two'straight-edges: a long, flat .bar 45, which supports and'is adjustably connected to along .bar. 46 of right-angular cross section. A

plurality of locking screws '4? are threaded'into openings 48 in the bar '45 and pass through elongated slots 49 in the horizontal flange 50 of the bard-6. The elongated slots 48 permit the bar 46 "to-slide upon the flat bar 45 when the screws 41 are loosened fora short distance in a direction limits or said has beenadjusted to a given opening, removed and placed upon the door or closure 53 which is to be fitted with the door or closure 53 resting in a horizontal plane on a bench or other form of support, and that thestraight edge assembly has .ting of doors or closures to openings. Due tothe flexibility of the device, its adaptation to profile work is a-matter of ordinarymechanical proce- I dure. The device in the form and-size referred to herein may be used without adaptation for a certain shapes and sizes of profiles for exami.

pl e, the fittings ,of shelves and/or cabinets in I room corners or closets. However, other classes I and sizes of Work may requirevarying sizes of the device, and variations in shape 'of thebars' and points. I l
